Suppose we want to make cuts in a circular pie (the usual kind of cut, from the center to a point on the perimeter) in such a way that, for every k between 1 and n, the pieces can be divided equally among k people, each of whom gets the same amount of pie.
Searching the OEIS for "cut pizza" ... "cut pie" [didn't help]
Alas, it has nothing to do with circularity of the item, so "pie", "pizza" mightn't work. But if it's a cut _cake_: A265286. IIRC, this was discussed on Seqfan. -- Don Reble djr@nk.ca
